Summarize some of the differences between the ARM architecture and the x86/x64 architecture from an instruction set perspective? How does their approach to multiple cores differ? What are some of the advantages of integrating a GPU on die with a CPU (aka an APU)? Why is this not done for the most powerful graphics processors? Describe some of the pros and cons of multiprocessor and multicore systems. Compare and contrast at least 3 features of both. Why are multiprocessor systems found almost exclusively in servers, while multicore systems are in all types of computers? What is a system on a chip? What features are typically included, and where would you be likely to find one? What are some disadvantages of SoCs? O. Describe parallel computing. How must programmers structure their code to run on massively parallel systems like supercomputers? Why are GPU programming and parallel computing often discussed in conjunction with each other?
